Fuel Types And Driveability Issues; Api Refueling Advisory; Engine Fan; Exhaust System Heat - Fleetwood Expedition 2009 Service Manual

Modern fuel systems may build up vapor pres-
sure within the tank as the fuel warms during
use or hot weather. Under certain conditions,
sudden release of this pressure when removing
the fuel cap can cause fuel to spray from the fill
opening, creating a fire hazard.
A.
WARNING
When removing the fuel fill cap, rotate
it
slowly only
far enough to allow the pressure to release. After any
"hissing" sound stops, remove the cap completely.
To protect the fuel system from excessive pres-
sure or vacuum, or from sudden release of pres-
sure, replace lost or damaged fuel fill caps with
caps of the same design which are available
from your Fleetwood motor home dealer.
Clean up fuel spills immediately. Fuel spilled on
the motor home could damage the exterior fin-
ish, and is a serious fire hazard.
NOTE
I
Fuel for the generator is taken from the main fuel tank
through
a
special feeder tube which is higher in the
tank than the feeder tube to the motor home engine.
This arrangement prevents the generator from run-
ning the motor home fuel tank dry.
Fuel Types and Driveability Issues
Your motor home's automotive fuel and emis-
sions systems are sophisticated and engineered to
meet Federal and State emissions standards. They
are sometimes sensitive to fuel types and blends,
patticularly fuels blended for ce1tain altitudes and
climates. Fuel suppliers provide customers with
the correct fuel for their location and seasonal
conditions. Sometimes, though, fuel blended for
winter is supplied during summer months.
API REFUELING ADVISORY
The American Petroleum Institute (API) offers
the following consumer advisOlY and safety
guidelines on vehicle refueling to help con-
On The Road
sumers avoid potential problems with refueling
and static electricity.
One of many possible causes of static electricity
build-up is reentering your vehicle during refu-
eling, particularly in cool or cold and dty cli-
mate conditions. This can cause a build-up of
static electricity similar to shuffling your feet on
the cat'Pet when the air in your home is dry. If
you return from your vehicle interior to remove
the filling nozzle without discharging the static
build-up, in rare circumstances, a brief flash fire
could occur at the filling point if the static
discharges and the resulting spark ignites fuel
vapors around the fill spout.
A simple precaution to help avoid this potential
problem is to stay near the vehicle's fueling
point. Do not get back into your vehicle during
refueling - even when using the nozzle's auto-
matic hold-open latch. If you must reenter your
vehicle, discharge the static electricity build-up
when you get out by touching the outside metal
portion of your vehicle, away from the filling
point, before attempting to remove the nozzle.
ENGINE FAN
When the engine is under load or requires maxi-
mum cooling, the engine fan turns faster. The
fan may become noisy at high speed and when
maximum cooling is required. High speed fan
noise can sometimes be misinterpreted as trans-
mission slippage. This is not the case. This fan
noise indicates that the fan is doing what it is
supposed to do. This noise is not a defect in the
fan or the transmission.
EXHAUST SYSTEM HEAT
Your motor home engine has been designed to
conform to Federal and State emission require-
ments. To meet these requirements, engine oper-
ating temperatures at'e high. As a result, the
engine, transmission and exhaust systems radi-
ate heat.
